SPECIFICATION forming part of Letters Patent No. 241,050, dated May 3,1881.

Application filed February 23, 1881.

T 0 all whom "it may concern:

Be it known that we, JAMES M. G. MoUoK and CHARLES F. GEORGE, ofFairfield, in the county of Jefferson and State of Iowa, have inventedcertain new and useful Improvements in Lamp-Burners; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enableothers skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inwhich- Figure l is a perspective view of our improved lamp-burner. Fig.2 is a vertical sectional view of the same, and Fig. 3 is a detail view,in perspective, of the lower part of the burner.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to lamp-burners; and it consists in certainimprovements in the construction of the same, which will be hereinafterfully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the perforated diaphragm orbridge, which is extended or continued to form an an nular flangesupporting the chimney-holding springs B, and has hinged thereto thecone, cap, or deflector O of the burner. The said cone, cap, ordeflector is provided near its base with one or more slots or apertures,D, the object of which is to prevent the lower part of the burner frombeing overheated by admitting the ingress of cold air.

The wick-tube is made in two parts, E F, the upper one of which, E, isfixed in diaphragm or bridge A, and the lower one in the cylinder G ofthe burner, which contains the screw or other mechanism, H, for raisingthe wick, and which is screw-threaded at its lower end, as shown at I,for attachment to the oil-reservoir of the lamp. This lower part of theburner is hinged to the under side of the extended diaphragm A at a byone of four arms, N, the outer bent ends of which are sprung into slotsin the rim of the flanged dia- (No model.)

phragm, as shown in Figs. land 2; and by reference to the last-namedfigure it will be seen that the upper section, E, of the wick-tube ismade flaring at its lower end, as shown at J, so as to enable the wickto be easily raised up through it, and also that it is slotted at itslower flaring part, as shown at t 1', below the diaphragm A, whichpermits air to enter the wick-tube at this point, and also permits theescape of oil, with which the wick may be ot'ercharged, as it enters theupper contracted part of the tube above its flaring mouth J. Thisconstruction of the wick-tube prevents its lower section, andconsequently the part of the burner in which said lower lower issecured, from bein g overheated.

The cylinder G is provided at its upper end with an annular rim, K,forming a cup-shaped receptacle, L, from which an opening or passage, M,adjoining the wiclet-ube, leads to the bottom of said cylinder G. Anyoil raised in the wick by capillary action while the lamp is notburning, as well as any oil that finds its way through the slots oraperturesz' in the upper section of the wick-tube, will escape into thecup L, and from thence find its way through opening M back to theoil-reservoir.

Explosions of lamps are frequently (almost invariably) caused either bythe excessive heating of the burner while in use or by the accidentalignition of the inflammable fluid raised through the wick-tube while thelamp is not lighted and flowing-over the burner. By our improvement anyaccident from these causes is rendered impossible. The only parts of theburner liable to become overheated--viz., the cap and the wick-tube-arepractically isolated from the lower part of the burner, and the oilraised by the wick and not consumed can escape only into the cup L, fromwhence it is bound to return to the oil-reservoir, thus not onlyavoiding danger, but also unnecessary waste of the illuminating-fluid,while at the same time cleanliness is vastly promoted.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States- In a lam p-burner, the combinationof the cylinder or ratchet-chamber Gr, having wick tube F and cup-shapedreceptacle L, provided with the passage M, hinged diaphragm A, havin gwick-tube E, provided with a fiarin g mouth, J, slotted at t '1', andhinged burner-cone (3, having a series of slots or apertures, D, at itsbase, substantially as and for the purpose herein shown and described.

In testimony that We claim the foregoing as ourown we have heretoaflixed our signatures in presence of two witnesses.
